The OneTouch® SelectSimple™ Meter displays messages and will beep when there are problems with the test strip, with the meter, or when your blood glucose levels are higher than 600 mg/dL or lower than 20 mg/dL. Messages do not appear in all cases when a problem has occurred. Improper use may cause an inaccurate result without producing an error message.
You may have a very low blood glucose level (severe hypoglycaemia), lower than 20 mg/dL.
What to do:
This may require immediate treatment according to your healthcare professional’s recommendations. Although this message could be due to a test error, it is safer to treat first and then do another test.
The meter has detected that the temperature is above or below the system operating range. Do Not perform a test until the meter and test strips reach a temperature within the operating range of 10–44°C.
What to do:
Repeat the test after the meter and test strips have reached a temperature within the operating range.
